Request for check for/confirmation of potential bugs in Debtree

[Renzo de Paoli]

Good afternoon.

I've been experiencing some issues with debtree on Kubuntu 24.04.1.
(debtree v1.1.2, installed via Kubuntu apt)

 1. debtree gcc-13-x86-64-linux-gnu:amd64
    Aborts with with error message
             "gcc-13-x86-64-linux-gnu:amd64" ->
    "c-compiler-x86-64-linux-gnu" [arrowhead=inv,color=green];
    Can't use string ("") as a HASH ref while "strict refs" in use at
    /usr/bin/debtree line 329.

 2. debtree g++-13-x86-64-linux-gnu:amd64
    Reports error message
             "g++-13-x86-64-linux-gnu:amd64" ->
    "c++-compiler-x86-64-linux-gnu" [arrowhead=inv,color=green];
    Use of uninitialized value in string eq at /usr/bin/debtree line 329.
    Use of uninitialized value in string eq at /usr/bin/debtree line 329.
    Use of uninitialized value in string eq at /usr/bin/debtree line 329.
             "c++-compiler-x86-64-linux-gnu" -> virt1
    [dir=back,arrowtail=inv,color=green];

This looks similar to the bug reported in here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=954795

I would appreciate it, someone else could check and see, if this is a 
genuine issue, or might be down to my installation only.
I would also like to know (if this is a bug), where this should be 
filed? Ubuntu, or Debian, or both?

Thanks in advance.

Best regards,
Renzo de Paoli
